Fertilizers, liming materials and inhibitors - Sampling and sample preparation - Part 1: General sampling provisions

This technical specification establishes comprehensive guidelines for the sampling and sample preparation of fertilizers, liming materials, and inhibitors. It outlines the fundamental principles and procedural requirements applicable to the generic collection of representative samples from various bulk lot sizes and forms. The document addresses critical aspects such as sampling plans, equipment selection, and techniques to ensure sample homogeneity and integrity throughout the extraction process. By adhering to these prescribed methods, stakeholders can achieve reliable analytical results that accurately reflect the quality and composition of the material under examination. The guidelines cover diverse scenarios encountered in industrial and agricultural settings, providing a unified approach to minimize sampling errors and variability. This framework serves as a foundational reference for laboratories, producers, and regulatory bodies engaged in quality assurance activities related to soil amendment products and nutrient supply materials.
